Herbicide application is a great way of killing most problem plant species but with Rhododendron Ponticum the size of the plant and the lack of systemic movement of herbicides down the stem to the root bole, makes spraying mature plants a very tricky prospect.
However by putting a more concentrated dose of herbicide directly into the plant stem it is possible to achieve very good results as the pictures above show.
The usual requirements for a suitably qualified operator apply and it’s crucial to apply an accurate dosage of herbicide. It’s a technique which isn’t that well suited to small and immature plants or plants which have been cut back and left to regrow because you need a sufficiently big stem to hold the herbicide but in the right conditions it’s a very fast and cost effective way of dealing with this problematic species.
